| 摘 要： | 为建立黄栀子上绿灰蝶的绿色防控体系,我们根据绿灰蝶引起的产量损失率和经济阈值建立了绿灰蝶防治指标模型,比较了不同农业措施对3个栀子品种上绿灰蝶的控制效果及生物和化学药剂的防治效果。结果表明,自然条件下3个栀子品种中黄栀子受绿灰蝶的为害最严重,受害率为38.3%。采取绿色防控处理,即每年12月初修剪并在来年3月中旬中耕除草的黄栀子上绿灰蝶的蛀果率最低;4种生物药剂中苏云金杆菌32 000 IU/mg WP 750倍液,3种化学药剂中90%敌百虫原药1 000倍液防效最高,分别达87.6%和85.1%,两种药剂单独使用时该害虫防治指标分别为4.44头/株和2.43头/株。

| Abstract: | To facilitate the green prevention and control technology against Artipe eryx on Gardenia jasminoides, control index were determined based on yield losses and the economic threshold. The control effects of different agricultural measures on A. eryx in three gardenia cultivars were compared, the control effects of biological and chemical insecticides against A. eryx on G. jasminoides were evaluated. The results showed that under natural conditions, the damage rate of G. jasminoides was 38.3%, the highest in the 3 gardenia varieties. Pruning at the beginning of December every year and weeding in the middle of next March in the green control treatment group showed the best control effect, with the lowest rate of decayed fruit on G. jasminoides. Bacillus thuringiensis 32 000 IU/mg WP 750 times and trichlorfon 90% TC 1 000 times had the highest control effect with the efficacy of 87.6% and 85.1%, respectively. In the case of single use of the two agents, control indexes against A. eryx were 4.44 and 2.43 individuals per plant, respectively. |
